I glanced over at the bank of phone booths. Should I call in? No backup from the detail was available anyway; even Sapperstein, the boss, was out in the field, over at Dearborn Station. I looked up at the silver-metal futuristic clock that loomed like a benignly neglectful God over the station’s sprawling waiting-room world: four-fifteen. Sapperstein would be heading back to the Detective Bureau soon.

Didn’t matter. I wanted this collar for myself, and right now. If it panned out, I didn’t want to share the glory. If it was a false alarm, then nobody need know. Should I go in the ladies’ room and grab her while she was changing a diaper? But what if it wasn’t her? Or worse, what if it was, and a bunch of innocent ladies got shot to shit with their scanties down around their ankles?

A Trib had been left on the pew next to me; I picked it up and pretended to read it. Even the inside pages were full of Lindbergh news. Dopes like me who thought they spotted the kid everywhere from Duluth to Timbuktu.

In less than two minutes, she exited the restroom as quickly as she’d entered.

I folded the paper, tossed it on the pew, yawned, and sauntered after her. She was headed for the stairwell.

Despite her armload, she bolted recklessly down the stairs toward street level like she was being pursued; which she was, only I hoped she didn’t know it. I followed her at an easy pace, buttoning my topcoat and snugging my fedora as I went. She had taken the stairs at the right. I took the ones at the left. I wanted to ease up behind her and slip on the cuffs.

When I got to the landing where the two stairways met, she was already gone. And when I took three steps at a time down to street level, hand sliding along the curving stainless-steel banister, I found she was still way ahead of me. I pressed through people huddled around the newsstand by the doors, and stepped outside, into an afternoon as gray as the city itself, icy snow flecking my face, Chicago’s famous wind earning its reputation. My breath rose before me like a wraith. The el tracks and station looming before me made the world darker and gloomier still. Where was she?
